NOTE:
(1) For SC5826-1, Switch OFF is VEN ≤ 0.8V and Switch ON is VEN ≥ 2.4V (“Active High”).
For SC5826-2, Switch ON is VEN ≤ 0.8V and Switch OFF is VEN ≥ 2.4V (“Active Low”).
For testing purposes EN will be 0V or VIN as applicable, unless otherwise specified.
(2) This device is ESD sensitive. Use of standard ESD handling precautions is required.
